[Cuis-dev] TrueType Fonts assignment

I'm a noob to Cuis, though I've been lurking awhile, and after watching
recent demos about progress on SVG I got an instance working on my Windows
machine using the 64 bit vm and Cuis5.0-4567.image. I tweaked preferences a
bit and found I liked everything about the experience *except* how TT fonts
had the return and assignment arrows looking like blocks, as noted by

I am unable to find the preferences you mention above, but figured out I
could add them to the preferences list, however they did not change
anything. So maybe I'm using the wrong image?

Don't get me wrong, I wouldn't mind if the left and up arrows were always
dynamically inserted by default when I type ^ or :=, but not until all the
supported fonts can render them properly. That would be my feedback. Until
then the default should be ^ for returning a value, and := for assignment.

The SVG support is a big deal and I'm interested in exploring what I can do
with Cuis as an alternative, but for most application needs Pharo and
Cincom, as "top heavy" as they are, still seem most suitable for actual
application development. Gemstone is also great. In general I am always
struggling with which to use for what purpose.
